Abstract
The utility model discloses a reheating coil cold energy recovering device of a constant-temperature and constant-humidity fresh air unit. The device comprises a communicating pipe, valves and the like. By communicating a preheating coil of the constant-temperature and constant-humidity fresh air unit with a reheating coil and introducing cold water in the reheating coil to the preheating coil through a connecting pipe, the temperature and humidity of inlet air of the cold water coil are reduced, and the load of the cold water coil is saved. The reheating coil cold energy recovering device of the constant-temperature and constant-humidity fresh air unit has the beneficial effects that not only can the amount of hot water used by the reheating coil be reduced, but also the cold energy of the cold water coil can be recovered and the operating cost is reduced.
Description
Technical field
the optimization that the utility model relates to a kind of constant temperature and humidity fresh air processor group improves, and can reclaim the cold consuming when fresh air processor group is freezed summer, and energy-saving effect is remarkable.
Background technology
at present, during known constant temperature and humidity fresh air processor group summer operation, by chilled water coil, carry out cool-down dehumidification, new wind is very low by temperature after chilled water coil cool-down dehumidification, need to again heat up by hot-water coil pipe, guarantee that fresh air processor air-supply humiture is constant, overall operation energy consumption is very high.
Summary of the invention
The utility model is a kind of cold energy reclamation device, comprise content: motor regulated valve, manual adjustments valve, connection manual adjustments valve, connecting pipe, circulating water strainer, by connecting pipe, motor regulated valve, manual adjustments valve, circulating water strainer, connection manual adjustments valve are connected, constant temperature and humidity fresh air processor group preheat coil is communicated with hot coil again, the low-temperature cold water of hot coil causes preheat coil by cold energy reclamation device again, with aerial temperature and humidity before the import of reduction chilled water coil, save chilled water coil load.The beneficial effects of the utility model are not only to reduce hot coil hot water use amount again, and can reclaim chilled water coil cold, save operating cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is constant temperature and humidity fresh air processor principle drawing
In figure, 1. motor regulated valve 2. manual adjustments valves 3. are communicated with manual adjustments valve 4. connecting pipe 5. circulating water strainers
the specific embodiment
The technical scheme that the utility model adopts is: in Fig. 1, motor regulated valve 1 is opened, manual adjustments valve 2 is closed, being communicated with manual adjustments valve 3 opens, cold water water outlet is by connecting pipe 4, before being connected to preheat coil water supply line circulating water strainer 5, in coil pipe low-temperature cold water by with fresh inlet contact heat-exchanging, reduce the humiture that new wind enters chilled water coil, reach the object of cold recovery.The beneficial effects of the utility model are not only to reduce hot coil hot water use amount again, and can reclaim chilled water coil cold, save operating cost.
Claims (3)
1. constant temperature and humidity fresh air processor group hot coil cold energy reclamation device again, it is characterized in that: by pipeline, constant temperature and humidity fresh air processor group preheat coil is communicated with hot coil again, new wind by chilled water coil after temperature reduce, by hot coil again, heat up, after hot coil contact Cryogenic air, temperature reduces again, by the pipeline connecting, cause preheat coil, reduce constant temperature and humidity fresh air processor group inlet air humiture, save chilled water coil load.
2. constant temperature and humidity fresh air processor group according to claim 1 hot coil cold energy reclamation device again, it is characterized in that: the new wind air-treatment of constant temperature and humidity unit preheat coil, chilled water coil, hot coil is copper pipe type heat exchanger again, preheat coil is arranged in constant temperature and humidity fresh air processor group wind inlet section, chilled water coil is arranged in interlude, then after hot coil is arranged in chilled water coil.
3. constant temperature and humidity fresh air processor group according to claim 2 hot coil cold energy reclamation device again, wherein constant temperature and humidity fresh air processor group comprises preheat coil, chilled water coil, hot coil again.
